Check accuracy of part made from Solidworks Import

3DMaker

Hello,

I am transferring some files from solidworks into onshape. I am remaking each one completely in onshape so that I will be able to edit them in the future in onshape. This is due to the fact that solidworks files imported into onshape do not have the entire feature tree as solidworks (sketches, extrusions, etc.).

My question is: how can I check how accurately I replicated the parts? Is there some sort of layover or subtraction technique in onshape which would tell me the specific differences in the two parts?

Thanks!

Ask'm about their volumes.

Since they're both parasolids, the difference will be zero. 

The trick is building in OS from dumb solids and not making references to the imported SW geometry.

Also, an understanding of analytic faces will help when building sketches in OS. Remember you can "use" edges to define sketch entities and then delete the "use" reference. ie.. if you use the edge of a cylinder in a sketch, it'll come in as a circle in the correct location & have the right diameter. Makes reverse engineering fast.

Rebuilding parametric models from dumb solids is quite easy and you can clean up poorly constructed parametric models.

Consider yourself lucky because you'll have some really well built geometry inside OS when done.

A boolean subtract (both ways) should create zero bodies. That would tell me that they are geometrically identical.
